In a user equipment of a wireless communication system, a method for signal transmission and reception may include: sending a request for a Circuit Switched voice network (CS) service to a Gateway Mobile Switching Center (GMSC) to send and receive data to and from a second user equipment; and receiving a call reject response corresponding to the service request from the GMSC, wherein the call reject response is sent by an entity in a core network of the second user equipment. According to an embodiment, it is possible to provide a suitable service to a sender terminal making a CS service request to a receiver terminal having subscribed only to a PS service without increasing network load.

Method for controlling service in radio communication system

In a device, there is provided a session management sublayer management and a mobility management sublayer. A session management message for managing a session according to a second standard is received at the device via communications according to a first standard. The mobility management sublayer provides to the session management sublayer an indication that the message was received according to the first standard. The session management sublayer provides an indication to the mobility management sublayer that a responsive session management message also associated with the session according to the second standard should be transmitted via communications according to the first standard.

Method and apparatus for achieving NAS signaling via other access

A method and apparatus for providing access control for mobile originated location requests, particularly, but not limited to, in 5G networks. An access attempt message triggered by a mobile originated location request or other 5GMM procedure may be assigned an access category based on whether a mobile originated location request procedure is ongoing or not ongoing. The message assigned the access category may be an LTE positioning protocol message. Possible access categories may include, for example, an MT_acc category for non-ongoing procedures and an MO_sig category for ongoing procedures, An access control check may be performed unless the mobile device switches from an idle to a connected mode.

Method and apparatus to control access attempts due to positioning

In some example embodiments, there may be provided a method that includes receiving, at a user equipment while being served by a first system and during protocol data unit session establishment or modification procedure, a message including an access point name aggregate maximum bit rate value; and when there is an inter-system change from the first system to the second system, setting, at the user equipment, the access point name aggregate maximum bit rate value of a session management context for the second system to the received access point name aggregate maximum bit rate value received while being served by the first system. Related systems, methods, and articles of manufacture are also described.

Session context conversion

An apparatus comprising: at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: determine that a user equipment is to switch from using a first radio access technology to using a second radio access technology to perform an emergency call; determine that the user equipment supports access to a core network via a cell of the second radio access technology; and cause the user equipment to switch from using the first radio access technology to the second radio access technology.

Apparatus, method and computer program for emergency call

A user equipment operating in a connected mode includes a first layer, a second layer, and a third layer. The first layer generates a request to send a non-initial non-access stratum (NAS) message over a first connection that operates according to a first radio access technology (RAT). The second layer determines whether access to the first connection is barred for the non-initial NAS message. The first layer selects a connection to deliver the non-initial NAS message between the first connection and a second connection that operates according to a second RAT in response to access to the first connection being barred. In some cases, the non-initial NAS message is a mobile originated short message service (SMS) message or an uplink NAS transport message. In some cases, the first layer is an NAS layer and the second layer is a radio resource control layer.

Access control for user equipment in a connected mode

A technique includes detecting, by a user device, a network slice associated with an access attempt by the user device to access a wireless network, and making, by the user device, a barring decision for the access attempt based on the network slice associated with the access attempt. Another example technique may include receiving, by a base station from one or more core network entities within a wireless network, network slice-specific load information that indicates a load for each of one or more network slices, determining, by the base station based on the received network slice-specific load information, a barring configuration that indicates a set of barring parameters for one or more access categories, and sending, by the base station to a user device, the barring configuration to reduce a load on the wireless network.

Network slice-specific access barring for wireless networks

An apparatus comprising: at least one processor: and at least one memory including computer program code: the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: receive () a fallback indication from a radio resource control layer: invoke () a service request procedure: and set () at least one of a service type information element and an uplink data status information element in a service request message.

Apparatus, method, and computer program for connection management

A method, apparatus and computer program product may be provided for providing always-on as an attribute of a PDU session, providing interworking aspects with respect to an always-on PDU session, and enabling network determination of whether a PDU session will be an always-on PDU session. An example method may include receiving, from UE, a PDU session establishment request message, the PDU session establishment request message comprising an always-on PDU session requested IE set to a value indicative of a request to establish a new-always on PDU session (e.g., 'Always-on PDU session requested'), and upon a determination that the requested PDU session shall be established as an always-on PDU session, cause transmission of a PDU session establishment accept message, the PDU session establishment accept message comprising an always-on PDU session indication IE that is set to a value indicative of always-on PDU session required (“Always-on PDU session required”).

Method and apparatus for providing an always-on attribute of a PDU session and for providing interworking aspects with respect to an always-on PDU session

An apparatus comprising means for performing: determining an expiration of a service request timer generated in association with a service request message from the apparatus; and handling the expiration of the service request timer based on a determination of a service type of the service request message.

Method, apparatus and computer program

There is provided an apparatus. The apparatus comprises means for performing: participating in a slice-specific authentication and authorization procedure for the apparatus; and receiving a message at the apparatus, the message comprising an information element indicating to a mobility management sub-layer of the apparatus a result of the slice-specific authentication and authorization procedure, and the message comprising single network slice selection assistance information for the apparatus.

Apparatus, method and computer program

The disclosure relates to a communication technique for converging, with an IoT technology, a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor.
